In a Wednesday, April 30, 2014 photo, Garry Smith, a Shepherd's Garden board member, holds a rendering of the Shepherd's Garden Park, near the corner of 6th and Jackson Street, the garden's site in downtown Sioux City. The Madison, Wisconsin-based Freedom From Religion Foundation said in a recent letter to Iowa officials that giving grant money to The Shepherd's Garden violates the U.S. and Iowa constitutions. Iowa Economic Development Authority spokeswoman Tina Hoffman said state money from the Vision Iowa grant would pay only for green space at the park and not for any of the project's religious elements.
